My girlfriends son is your typical, pasty skinned, reclusive, 15 year old computer hacker. He has some way of spying on all the websites that my girlfriend surfs to, along with being able to spy on all her I.M. chats. He's doing this remotely from his fathers, on his own computer. She tells me that he supposedly hasn't installed any software on this pc of hers that I'm using, to do whatever the hell it is he's doing. She's running windows xp and he told her that it's a hack that's inherent to all xp software. This isn't a problem for me; just yet, since I'm running a dinosaur P2/300mhz with win95 but, if you guys read another thread I've posted on here, you'll see I'm about to step up to the plate, buy a new pc and, I'll be stuck with winxp...and the nosey little hacker. Do any of you guys have ANY idea what this hack is he's talking about? I want to make sure the little bastard doesn't get one over on me!!!! We have a dsl connection here and supposedly he knows our ip number and uses this somehow to do his spying. Do I have to go out and buy some anonymizer software? A firewall? What do I have to do to make sure this snot nosed teen gets the short end of the stick when dealing with me. Any help from you guru's is EXTREMELY appreciated!!!!!
